Tickets for the sold out show at the Echoplex in Echo Park were $20 apiece, a fraction of what tickets to their "50 and Counting" tour will cost when it launches May 3 at Staples Center. The lowest-priced tickets were going for $250 each.
Hundreds of fans lined up outside the El Rey Theatre earlier Saturday for a chance at the tickets, which were dispensed through a lottery system. Buyers were limited to one ticket, and were required to show a government-issued ID, pay with cash, wear a wristband with their name on it and be photographed. Their names were verified at the Echoplex, which has a capacity of about 700.
"I was on Twitter this afternoon and I just saw a tweet that was just like, Stones concert ... so I grabbed my dad, we ran down to the El Rey, got in line and we just got in the lottery and won," said Eve Dorfman.
Rumors of the spontaneous show spread across social networks this week after the band teased the appearance on their Twitter accounts.
